Data centers are black boxes, but California wants to change that

California Governor Gavin Newsom signed seven bills aimed at increasing transparency around data centers' impact on electricity bills and water supplies. The legislation requires monthly energy consumption reporting (AB 1577), separate power rates for data centers to prevent cost-shifting to other consumers (SB 886, AB 2383, SB 1168), water disclosures (AB 2619, AB 2469), and environmental review requirements by eliminating categorical exemptions from the California Environmental Quality Act (SB 887). Researchers from the Union of Concerned Scientists and Santa Clara University have highlighted the critical lack of data: all water providers in districts housing data centers refused to share usage data citing privacy regulations, and very few data centers have public environmental impact reports.

The laws still leave significant gaps — water disclosures are only required during permit or business license applications, not annually — but experts consider them a meaningful step forward. As AI-driven hyperscale data centers move into rural areas, small water systems and lower-income communities may struggle with increased demand. While data centers could theoretically lower electricity costs by spreading fixed grid maintenance costs across more customers, they may also increase costs through expensive new infrastructure needs and the risk of overbuilding if the AI bubble bursts. Without better data, it remains unclear which scenario is unfolding in California.
